Watercolour Challenge is Channel 4's daytime series featuring amateur painters. Presented by Hannah Gordon, the show travels to some of the most beautiful parts of the British Isles and challenges local artists to paint a scene from a chosen area in just four hours. For some this is a terrible rush - for others it is just too long. All have their distinctive style - some representational, some expressionists, some abstract - and with such a range of subjects, Diana Vowles has the opportunity to discuss all aspects of watercolour as she meets so many different painters.
